Question

A floor is 8 m long and 5 m wide. A square carpet of sides 4 m is laid on the floor. Find the

area of the floor that is not carpeted​

Answer 1

Answer:

$length \: of \: floor = 8m \\ breadth \: of \: floor = 5m \\ area \: of \: floor = l \times b \\ 8 \times 5 = 40 {m }^{2}$

$sides \: of \: carpet = 4 \\ area \: of \: carpet = side \times side \\ 4m \times 4 m\\ 16 {m}^{2}$

$area \: of \: floor \: not \: covered = area \: of \: floor - area \: of \: carpet \: \\ = 40 {m}^{2} - 16 {m}^{2} \\ = 24 {m}^{2}$
